Description

本発明は、筆記具を把持する部分に取り付けられるグリップに関するものである。   The present invention relates to a grip attached to a portion that holds a writing instrument.

従来、筆記具を把持する部分に取り付けられたグリップとしては、内方層と表面層との上下に積層した軟質材で形成し、内方層のショアー硬度がＨｓ（ＪＩＳ Ａ）５〜３０、表面層のショアー硬度がＨｓ（ＪＩＳ Ａ）４０以上で構成した筆記具のグリップが知られている。（特許文献１参照）
特開２０００−３５５１８５号公報 Conventionally, a grip attached to a portion for holding a writing instrument is formed of a soft material laminated on the upper and lower layers of the inner layer and the surface layer, and the Shore hardness of the inner layer is Hs (JIS A) 5 to 30, There is known a grip of a writing instrument having a layer having a Shore hardness of Hs (JIS A) 40 or more. (See Patent Document 1)
JP 2000-355185 A

しかしながら、上記した筆記具のグリップは、内方層と表面層の間に空間部がなく、手で把持した時に十分な弾性変形が得られなかった。
本発明は、上記課題を解消する筆記具のグリップを提供することを目的とするものである。 However, the grip of the writing instrument described above has no space between the inner layer and the surface layer, and sufficient elastic deformation cannot be obtained when gripped by hand.
An object of the present invention is to provide a grip for a writing instrument that solves the above-described problems.

本発明は、筆記具を把持する部分に取り付けられるグリップにおいて、そのグリップを、軟質材からなる内グリップと軟質材からなる外グリップの二層構造で構成し、前記内グリップの両端に外鍔を形成し、かつ、内グリップの表面に複数の突部を形成し、内グリップの２つの外鍔により内グリップを外グリップに嵌合し、内グリップの表面と外グリップの内面の間に適宜の空間部を構成するとともに、内グリップに形成した突部を根元が太く先端に行くに従って細くなるように構成したことを第１の要旨とする。 The present invention relates to a grip attached to a portion for holding a writing instrument, and the grip is composed of a two-layer structure of an inner grip made of a soft material and an outer grip made of a soft material, and outer ridges are formed at both ends of the inner grip. In addition, a plurality of protrusions are formed on the surface of the inner grip, the inner grip is fitted to the outer grip by two outer flanges of the inner grip, and an appropriate space is provided between the inner grip surface and the inner surface of the outer grip. The first gist is that the projecting portion formed on the inner grip is configured such that the root is thicker and narrows toward the tip.

また、内グリップに形成した突部を山形に形成したことを第２の要旨とする。   Further, the second gist is that the protrusion formed on the inner grip is formed in a mountain shape.

更にまた、外グリップを透明性を有する軟質材で構成したことを第３の要旨とする。
Furthermore, the third gist is that the outer grip is made of a soft material having transparency.

本発明は、内グリップの表面に複数の突部を形成して内グリップの表面と外グリップの内面の間に適宜の空間部を構成することにより、手で外グリップを把持した時に外グリップが十分に弾性変形をするので非常に柔らかい感触が得られる効果が奏せられるものである。更に、内グリップに形成した突部を根元が太く先端に行くに従って細くなるように構成することにより、握った時の押圧力を突部が下方にのみ変形して受けるので、外グリップがねじれたり円周方向に寄せられたりして筆記を妨げる恐れも生じないものである。   According to the present invention, a plurality of protrusions are formed on the surface of the inner grip, and an appropriate space is formed between the surface of the inner grip and the inner surface of the outer grip. Since it is sufficiently elastically deformed, the effect of obtaining a very soft feel can be obtained. Furthermore, by configuring the protrusion formed on the inner grip so that the root is thicker and narrower as it goes to the tip, the protrusion receives only the downward pressing force when it is gripped. There is no danger of disturbing writing by being pushed in the circumferential direction.

内グリップの表面と外グリップの内面との間に適宜の空間部を構成することにより、外グリップを把持した時に外グリップが弾性変形をして把持し易い筆記具のグリップを実現した。   By configuring an appropriate space between the inner grip surface and the inner surface of the outer grip, the grip of a writing instrument that is easy to grip due to elastic deformation of the outer grip when the outer grip is gripped is realized.

以下、図１及び図２に基づいて本発明における実施例１の筆記具のグリップを説明する。先ず、着色した軟質材で作製された内グリップ１の表面に複数の突部１Ａを略等間隔に形成する。この突部１Ａの断面形状は、根元が太く先端に行くに従って細くなるように山形に構成する。また、内グリップ１の前端と後端に外鍔１Ｂを形成する。次に、透明あるいは着色透明からなる軟質材で作製された外グリップ２の前端に内鍔２Ａを形成する。また、外グリップ２の外形は両端から中間部に向かって徐々に曲線状に細径に形成されている。この外グリップ２を前記内グリップ１に被せることにより、筆記具のグリップを構成する。   Hereinafter, based on FIG.1 and FIG.2, the grip of the writing instrument of Example 1 in this invention is demonstrated. First, a plurality of protrusions 1A are formed at substantially equal intervals on the surface of the inner grip 1 made of a colored soft material. The cross-sectional shape of the protrusion 1A is formed in a mountain shape so that the base is thick and narrows toward the tip. Further, an outer collar 1B is formed at the front end and the rear end of the inner grip 1. Next, the inner collar 2A is formed at the front end of the outer grip 2 made of a soft material made of transparent or colored transparency. Further, the outer shape of the outer grip 2 is gradually reduced in diameter from both ends toward the middle portion. The outer grip 2 is put on the inner grip 1 to constitute a writing instrument grip.

次に、図３により本発明の筆記具のグリップをノック式シャープペンシルに設けた例で説明する。先ず、チャック３の頭部３Ａを複数に分割して拡開可能に形成し、この頭部３Ａにテーパー面を形成する。前記チャック３の頭部３Ａに締リング４を外嵌し、チャック３の後部にパイプ状の芯タンク５を圧入固着する。また、締リング４を受け止めるワッシャー６と芯タンク５の間にスプリング７を張架し、チャック３のテーパー面が締リング４に押圧され機構部が構成される。   Next, an example in which the grip of the writing instrument of the present invention is provided in a knock mechanical pencil will be described with reference to FIG. First, the head 3A of the chuck 3 is divided into a plurality of parts so as to be expanded, and a tapered surface is formed on the head 3A. A fastening ring 4 is fitted on the head 3A of the chuck 3 and a pipe-shaped core tank 5 is press-fitted and fixed to the rear part of the chuck 3. Further, a spring 7 is stretched between the washer 6 for receiving the tightening ring 4 and the core tank 5, and the taper surface of the chuck 3 is pressed against the tightening ring 4 to constitute a mechanism portion.

軸筒８の前部８Ａは細径に形成され、この前部８Ａに前記内グリップ１を外嵌する。次に、内グリップ１に前記外グリップ２を外嵌する。すると、内グリップ１の外鍔１Ｂ及び突部１Ａが外グリップ２の内面に接触し、内グリップ１の表面と外グリップ２の内面の間に適宜の空間部が構成される。   A front portion 8A of the shaft cylinder 8 is formed with a small diameter, and the inner grip 1 is fitted on the front portion 8A. Next, the outer grip 2 is fitted on the inner grip 1. Then, the outer collar 1 </ b> B and the protrusion 1 </ b> A of the inner grip 1 come into contact with the inner surface of the outer grip 2, and an appropriate space is formed between the surface of the inner grip 1 and the inner surface of the outer grip 2.

この軸筒８の前方より前記機構部を挿入した後、軸筒８に口金９を螺合し、口金９の内段９Ａと軸筒８の前端でワッシャー６を挟持する。また、口金９が螺合されることによって口金９の後部９Ｂに取り付けられたリング１０と軸筒８の外段８Ｂによって外グリップ２が挟持され、外グリップ２の内鍔２Ａと軸筒８の前部外段８Ｃにより内グリップ１が挟持される。   After the mechanism portion is inserted from the front side of the shaft tube 8, the base 9 is screwed into the shaft tube 8, and the washer 6 is held between the inner stage 9 </ b> A of the base 9 and the front end of the shaft tube 8. Further, the outer grip 2 is sandwiched between the ring 10 attached to the rear portion 9B of the base 9 and the outer stage 8B of the shaft tube 8 by screwing the base 9, and the inner flange 2A of the outer grip 2 and the shaft tube 8 are The inner grip 1 is clamped by the front outer stage 8C.

更に図４に示したように、軸筒８に連結される内鞘１１に内グリップ１の突部１Ａと合わされる模様を転写、印刷するか、あるいは模様を付した加飾筒を内鞘１１に被せたり、さらには模様を印刷したシール１２を内鞘１１に貼り付けたりして取り付ける。この内鞘１１には透明の外鞘１３が被せられてシール１２の模様が目視可能に構成される。更に、外鞘１３の後部には転がり防止のための隆起部１３Ａが形成され、この隆起部１３Ａに開口孔１３Ｂが形成されてノック式シャープペンシルが構成される。   Further, as shown in FIG. 4, a pattern to be combined with the protrusion 1 </ b> A of the inner grip 1 is transferred to the inner sheath 11 connected to the shaft tube 8, or a decorative tube with a pattern is attached to the inner sheath 11. A seal 12 printed with a pattern is attached to the inner sheath 11 and attached. The inner sheath 11 is covered with a transparent outer sheath 13 so that the pattern of the seal 12 is visible. Further, a protruding portion 13A for preventing rolling is formed at the rear portion of the outer sheath 13, and an opening hole 13B is formed in the protruding portion 13A to constitute a knock type mechanical pencil.

この実施例１の場合には、内グリップ１に等間隔で複数形成された突部１Ａが、根元が太く先端に行くに従って細くなるように山形に形成しているので、外グリップ２を押圧した力は内グリップ１の突部１Ａによって下方にのみ変形して受けるので、外グリップ２が円周方向にねじれる恐れはない。また、突部１Ａが山形に形成されることにより、デコボコした感触が緩和されより柔らかい感触が得られる。   In the case of the first embodiment, the plurality of protrusions 1A formed at equal intervals on the inner grip 1 are formed in a mountain shape so that the base is thick and narrows toward the tip, so the outer grip 2 is pressed. Since the force is deformed and received only downward by the protrusion 1A of the inner grip 1, there is no possibility that the outer grip 2 is twisted in the circumferential direction. Further, by forming the protrusion 1A in a mountain shape, the uneven feel is alleviated and a softer feel is obtained.

尚、上記実施例１は、内グリップ１に形成した突部１Ａが山形に形成されているが、本発明は上記実施例に限定されるものではなく、突部を半球状に形成したり、あるいは断面が台形状に形成しても本発明の目的及び効果が十分に得られるものである。   In the first embodiment, the protrusion 1A formed on the inner grip 1 is formed in a mountain shape, but the present invention is not limited to the above embodiment, and the protrusion is formed in a hemispherical shape, Alternatively, even if the cross section is formed in a trapezoidal shape, the objects and effects of the present invention can be sufficiently obtained.

また、上記実施例１は、円周方向等間隔に複数形成された突部１Ａが、長手方向に隣り合う突部１Ａは互い違いに形成されているが、本発明は上記実施例１に限定されるものではなく、長手方向に同じ列に並べられても良いし、間隔が狭い部分と広い部分が任意に混在していても良い。   Further, in the first embodiment, a plurality of protrusions 1A formed at equal intervals in the circumferential direction and the protrusions 1A adjacent in the longitudinal direction are alternately formed. However, the present invention is limited to the first embodiment. They may be arranged in the same row in the longitudinal direction, and a portion having a narrow interval and a portion having a wide interval may be arbitrarily mixed.

更に、上記実施例１は、内グリップ１の突部１Ａが外グリップ２の内面に接触して構成されているが、内グリップの突部は必ずしも外グリップの内面に接触している必要はなく、隙間が設けられていても本発明の目的は十分に得られるものである。また、外グリップの外形は、中間部を太径にしたりあるいは単に円筒形にしたり、断面形状を三角形にしたり、肉厚を任意に変えたり等、種々の形状が考えられる。   Further, the first embodiment is configured such that the protrusion 1A of the inner grip 1 is in contact with the inner surface of the outer grip 2, but the protrusion of the inner grip is not necessarily in contact with the inner surface of the outer grip. Even if a gap is provided, the object of the present invention can be sufficiently obtained. Also, the outer shape of the outer grip may be various shapes such as the middle portion having a large diameter, or simply a cylindrical shape, the cross-sectional shape being triangular, or the wall thickness being arbitrarily changed.

更にまた、外グリップを透明な軟質材で形成するとともに内グリップも透明な軟質材で形成すれば、軸筒が透けて見えるので新たな外観が表現できる。   Furthermore, if the outer grip is formed of a transparent soft material and the inner grip is also formed of a transparent soft material, a new appearance can be expressed because the shaft tube can be seen through.

更にまた、内グリップは、硬さ（ＪＩＳ Ａ）１０、３０あるいは５０といったシリコンラバーや、硬さ（ＪＩＳ Ａ）３０、５０あるいは７０といったエラストマーが考えられる。これらの内グリップと組み合わされる外グリップとしては、硬さ（ＪＩＳ Ａ）５０のシリコンラバーを用いることによって、種々の柔らかさのグリップが設定可能となる。   Furthermore, the inner grip may be a silicon rubber having a hardness (JIS A) 10, 30 or 50, or an elastomer having a hardness (JIS A) 30, 50 or 70. As the outer grip combined with these inner grips, various soft grips can be set by using silicon rubber having a hardness (JIS A) of 50.

更にまた、本発明の筆記具のグリップは、ノック式シャープペンシルに限定されるものではなく、ボールペン等種々の筆記具に利用できるものである。   Furthermore, the grip of the writing instrument of the present invention is not limited to a knock-type mechanical pencil, but can be used for various writing instruments such as a ballpoint pen.

筆記中に、外グリップがねじれたり移動したりしない筆記具のグリップにすることができる。   During writing, the grip of the writing instrument can be made such that the outer grip does not twist or move.
